The historical past of the BMW roadster dates again to the early starting of the corporate. Some of probably the most outstanding fashions recognized by each BMW fanatic are the BMW 328 or the BMW 507. Today, BMW’s basic roadster legacy lives on with the most recent era of the BMW Z4.
And that’s not essentially so apparent. In latest years, gross sales numbers confirmed an incredible distinction between the open two-seater and an everyday sedan or SUV. While BMW of North America was in a position to promote greater than 70,000 items of the X3 by the top of December 2019, the gross sales numbers of the all-new Z4 didn’t even attain 3,000 items. To be exact, the Bavarians offered 2,941 vehicles of the brand new Z4 within the United States. Consequently, BMW determined to collectively develop the most recent era of the Z4 along with Toyota. This helps with growth prices and makes it doable to deliver the brand new Z4 onto the road.
A Road Trip To The Alps
In order to learn how the all-new era of the BMW Z4 performs on the street, we took out the highest model of the mannequin vary, the BMW Z4 M40i, for a spirited street journey within the Bavarian, Austrian, Italian and Swiss Alps. The strongest mannequin of the Z4 lineup options M particular choices, such because the M Sport brakes, the adaptive M Sport suspension and the electronically-controlled M Sport differential. In addition, mannequin particular design parts of the Z4 M40i embody the trapezoidal exhaust tailpipes and a Cerium Grey end for the outside mirror caps.
The inside of the Z4 is dominated by BMW’s newest design speech and continues to characteristic a driver-oriented dashboard. If you might be acquainted with the most recent BMW design language, you’ll instantly really feel at house and acknowledge numerous buttons and switches from different fashions, such because the BMW 3 Series. The variations begin with the distinctive leather-based seats and the decrease seating place. But that’s it.
A way more spectacular change occurred on the skin. The new Z4 owes its look to the Australian automobile designer Calvin Luk, who has additionally designed the present era of the BMW X3. From a design perspective there are barely any similarities with the earlier era, if in any respect. Okay, to be honest, the brand new Z4 roadster nonetheless embodies conventional BMW roadster components, equivalent to a protracted engine hood and air breathers behind the entrance wheel arches.
The entrance is clearly dominated by large air intakes and a broad kidney grille. For the primary time ever, the headlight items are positioned on the outer edges above one another. The aspect line of the Z4 is outlined by two character strains, which begin on the aspect finish of the hood and on the air intakes. Both strains finish on the rear which is dominated by the aspect surrounds, the exhaust pipes, the L-shaped headlights and the boot lid’s harmoniously built-in spoiler.
My brief time period check automobile featured Frozen Grey II metallic paint as exterior coloration. In the start I used to be a bit skeptic in regards to the frozen paint, however over the course of the week with the Z4 I began to prefer it an increasing number of. It definitely regarded nice together with the Vernasca cognac leather-based of the inside. The Z4’s total look was accomplished by the 19-inch double-spoke wheels painted in black and different blacked out design cues, thanks to the BMW Individual high-gloss shadow line. The non-compulsory high-gloss shadow line features a black kidney body, a black kidney grille in mesh design in addition to covers for the aspect air intakes and roll bar in high-gloss black and tailpipe trims in black chrome.
The Marvelous B58 Six-Cylinder
The BMW Z4 M40i is powered by BMW’s B58, a turbocharged six-cylinder in-line petrol engine. It’s the second time that I’m in a position to check drive a BMW with this masterpiece of engine know-how. Earlier this yr I had the pleasure to benefit from the capabilities of this engine with a BMW M340i xDrive Touring. Back then I used to be already thrilled by what it may well do. But my time with the Z4 M40i was even taking this to one other stage. But let’s have a fast take a look at the numbers first.
The B58 engine produces a complete energy output of 340 HP (250 kW) between 5,500 to 6,500 rpm and provides a most torque of 500 Nm (369 lb-ft) which is already out there as little as 1,600 rpm and up to 4,500 rpm. This huge and constant supply of pulling energy permits the Z4 M40i to hit the 100 km/h (62 mph) mark already after 4.5 seconds. This is simply 0.2 seconds slower than the outgoing BMW M3 F80! At the higher finish of the velocity vary, the highest velocity of 250 km/h (155 mph) is electronically restricted.
But subsequent to spectacular figures, the B58 options additionally cutting-edge engine know-how, equivalent to a water-cooled exhaust manifold which is built-in into the cylinder head and improved direct gasoline injection. The newest era of Piezo injectors is working with an elevated most strain of 350 bar and injects very small quantities of gasoline into the combustion chamber. This allows the Z4 M40i to obtain a gasoline financial system of seven.1 to 7.4 liter per 100 kilometer (31 to 33 mpg) within the WLTP check cycle.
Although the European model of the Z4 M40i is fitted with the necessary Otto particulate filter, I used to be pleasantly stunned by the exhaust sound (again in March I used to be fairly disillusioned by the sound of the M340i xDrive Touring). The Z4 M40i delivered precisely the sound word which you’d anticipate from a roadster with a sporty character. Especially in SPORT and SPORT PLUS the exhaust system created a deep and growly sound.
Next to the Z4’s superior engine, the automobile additionally boosts all newest tech stuff which the Bavarians have out there of their know-how package for his or her M Performance vehicles. A characteristic which comes commonplace and really helpful on the similar time is the electronically-controlled M Sport differential. Especially in case you are out with the Z4 and hunt one curve after the opposite. When cornering, the wheel on the skin of the curve covers an extended distance and subsequently turns quicker than the wheel on the within. In this explicit second, the M Sport differential creates a locking impact so as to equally distribute the drive torque and compensates for the distinction in velocity.
Driving the BMW Z4 M40i
My journey began within the environment of Munich the place I loved calm Friday morning on the street. The meadows and forests had been nonetheless coated with the damp morning dew and there have been hardly another vehicles on the way in which south in the direction of the Alps. Thanks to the electrically-operated delicate high I used to be in a position to retract the roof inside solely 10 seconds and will instantly benefit from the first sunshine of the day.
Already on the primary kilometers of the winding nation roads the BMW Z4 M40i was keen to showcase all its qualities. It goes with out saying that I primarily saved the Z4 M40i in SPORT or SPORT PLUS mode whereas driving. It was merely the easiest way to get pleasure from all these curvy roads.
Massive torque and pulling energy made it straightforward to overtake slower vehicles within the blink of a watch whereas the B58 provided a superb energy supply throughout the whole rpm vary. If I hadn’t stopped urgent the accelerator pedal, the Z4 M40i would have always and ceaselessly speed up up to the electronically restricted high velocity. It’s merely breathtaking how clean, spontaneous and on the similar time sturdy and consequent this engine delivers its energy.
But all the ability could be ineffective, if the B58 engine and the eight-speed sport computerized transmission wouldn’t work so harmoniously collectively. It saved the automobile all the time in the appropriate gear and I by no means felt the necessity to use the paddle-shifters on the steering wheel so as to power the automobile to use a distinct gear. The M-specific tune of the straight six-cylinder and the automated transmission was effectively noticeable.
Next to energy and energy distribution, the sharp, direct and exact steering performed an ideal position to additional enrich my driving expertise. Especially in case you drive one mountain move after the opposite, like I did, you’ll instantly worth such an ideal steering accuracy. While driving the mighty Passo Stelvio (Stilfserjoch) in Italy, it felt like I used to be in a position to maneuver the Z4 into the curve with centimeter precision.
Overall when it comes to driving dynamics, the Z4 M40i is well outplaying its predecessor. But the good engine together with the automated transmission and direct and sharp steering are solely half of the story. A effectively balanced and preferrred weight distribution of fifty:50, the usage of light-weight development elements (such because the soft-top) and a low heart of gravity are additional contributing to a dynamic and sporty roadster feeling.
Aside from the pure driving expertise, the Z4 M40i can also be a real journey companion. The baggage compartment is ready to swallow 50% extra luggage and journey instances in contrast to the outdated mannequin, independently if the soft-top is open or closed. Another new characteristic I discovered very helpful was the brand new cupboard space positioned behind the seats with a retaining web. Among different issues I might retailer my jacket and my water bottle there, which in any other case would most likely solely have flown round within the cabin.
In a nutshell, the 2020 BMW Z4 M40i is a tribute to sheer driving pleasure. It combines the pulling energy of a sports activities automobile with all benefits of a roadster. Never earlier than have I skilled such an ideal symbiosis of agility, energy and exact dealing with in a single package deal. The Z4 M40i completely integrates the motive force and makes you are feeling absolutely related to the street. If you want to speed up rapidly, in case you like to hunt curves on a sunny day with the highest down and in case you search for a automobile with exact dealing with, the Z4 M40i is your excellent companion.

Yes, in concept each Bimmer fanatic ought to get his fingers on a Z4 M40i and benefit from the sheer driving pleasure this automobile stands for. It embodies all traits of the last word driving machine. But in actual life, it gained’t be everybody’s first selection. And that’s a pity. The 2020 BMW Z4 M40i begins within the United States at a worth level of $63,700. My check automobile, which was principally absolutely loaded, sells for 78,090 EUR in Germany, which is round $92,860 transformed with the at this time’s alternate price. That’s definitely no small sum.
On the opposite hand you get a BMW roadster, which is really dwelling up to the genes of the corporate with the blue and white roundel.
